GLASS ORNAMENTATION.

SPECIFICATION forming part'of Letters Patent No. 324,133, dated August 11, 1885.

Application filed March .24, 1885.

To all whom it may concern:

Be it known that I, GEORGE A. MAOBETH, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Glass Ornamentation, of which improvements the following is a specification.

In the accompanying drawing, which makes part of this specification, the figure is a view in elevation of a chimney having affixed thereon my improved mark or design.

My invention relates to an improved method of affixing labels, trade-marks, and other designative marks or signs upon chimneys, globes, or other like articles of glass or porcelain used around or in connection with lamps or gasburners, and the object of my invention is to so affix such marks or signs that they will be reasonably permanent and at the same time will not interfere materially with the transparency of the articles upon which such marks may be placed; and to these ends my invention consists in the method substantially as hereinafter described and claimed.

Heretofore labels, trade-marks, &c., have been afiixed either by being printed on paper, which was then pasted onto the chimney or other article, or such marks were etched upon the surface of the article to be marked. The objection to the first method of marking is the necessarily temporary character of the mark or label, arising from the ease with which it can be removed and the necessity of its removal before the article is used, as such mark is opaque and consequently interferes with the passage of light through the chimney or other article on which it is placed. The other method of affixing these marks-71. 0., by etchingis objectionable for the reason that it requires considerable time to effect it and is expensive. I

In carrying out my improved method I mix together balsam and any suitable varnish, and add thereto sufficient, bronze-powder to make a comparatively thin paste. This compound, after being mixed or in the mixing operation, is spread upon a glass or marble slab, and is then transferred by a rubber or other suitable roller to a stamping-pad. After the chimneys or other articles have been annealed and are ready for market, the label or mark is (No model.)

stamped upon the chimney by means of a rubber or any other elastic stamp having the desired figure, mark, or letter formed on its face in alto-rilievo, said stamp being first pressed or stuck upon the prepared pad. As the rubber stamp will take up only a small portion of the bronze compound, and when pressed upon the chimney will part with only a portion of that which adheres to it, it follows that an exceedingly thin coating of the compound will be placed upon the chimney or other article, and as these marks or signs are usually in outline, the transparency of the chimney is but slightly impaired, hence the marks may be stamped any place upon the article. After being applied to the chimney the coating dries quite quickly; but the balsam prevents a too rapid drying of the varnish on the pad, and as it is somewhat sticky, aids in causing the bronze powder to adhere to the glass.

Only sufficient quantity of the bronze powder should be mixed with the balsam and varnish to render the mark visible; if the powder is used in large .quantities the mark will become opaque.

The ingredients should be used in such proportions as to render the compound capable of being spread, but it should be sufficiently thick to prevent its running when applied to the chimney.

Marks or labels as thus applied are orna mental and quite durable, and do not in any Way interfere with the use of the article to which they are applied.

I claim herein as my invention- 1. The method of affixing trademarks, labels, or ornamental designs to lamp-chimneys or other glass articles by stamping or printing the mark or design desired on each chimney or other article with a quickly-drying bronzing material, substantially as set forth.

2. As a new article of manufacture, a lampchimney or other like article having a trademark, label, or other design of bronze stamped or printed thereon, substantially as set forth.

In testimony whereof I have hereunto set my hand.

' GEORGE A. MACBETH.
